FFT Bin Calculator
Find FFT bin spacing, the nearest one-sided bin and its frequency error.
Open toolShelf Spacing Calculator
Find the equal clear gaps around interior shelf boards. Provide Inside space height, Interior shelf boards, Board thickness to compute results directly in your browser. Gap = (inside height - shelf count*board thickness)/(shelf count+1). Same length unit; shelf stack must fit. Does not assess structural loads. Inputs and results use floating-point numbers; output shows up to 12 significant digits. Rounding can occur.

Practical Worked Examples for Shelf Spacing Calculator
These concrete scenarios illustrate how the Shelf Spacing Calculator processes baseline inputs, comparison checks, and boundary constraints.
Baseline run (Inside space height = 100)
Inside space height = 100; Interior shelf boards = 3; Board thickness = 2. The displayed output is 23.5 length units.
Comparison scenario (shelf spacing calculator mm)
Inside space height = 80; Interior shelf boards = 3; Board thickness = 4. The displayed output is 17 length units.
Boundary & unit check (Shelf Spacing Calculator)
When solving for 'shelf spacing calculator', verify that Inside space height, Interior shelf boards, Board thickness use consistent units and stay within the documented scope: Gap = (inside height - shelf count*board thickness)/(shelf count+1). Same length unit; shelf stack must fit. Does not assess structural loads. Inputs and results use floating-point numbers; output shows up to 12 significant digits. Rounding can occur.
How to Read and Verify the Shelf Spacing Calculator Output
The output panel reports the exact result derived from Inside space height, Interior shelf boards, Board thickness alongside any unit or formatting notes.
The result is the equal clear gap between the opening edges and shelves. Lay out uniformly spaced interior shelf boards inside a given opening.
Clear gaps exclude board thickness and include the gaps at the top and bottom of the opening.
Numerical output shows up to 12 significant digits. Floating-point arithmetic and display rounding can affect the last digits.
- Example input
- Inside space height = 100; Interior shelf boards = 3; Board thickness = 2
- Example output
- 23.5 length units
